The Abu Dhabi Blue Carbon Demonstration Project

The key to this success has been the project’s ability to regard challenges to the original concepts as learning opportunities and integrate these into the scope of the Demonstration Project. Examples of these are expressed in Table 1.

Learning opportunity gained and how the project evolved to ensure its integration As the algal mats were identified as potential Blue Carbon ecosystems, a first for the region and world, this consideration was added to the project. The Ecosystem Services Assessment was based on available information and extrapolation of economic analyses from other regions. Recommendations based on best international practice and a local appreciation of ecosystem services and development pressures were made to guide future studies to comprehensively value market and non-market services. The realisation of the importance of blended ecosystem services in which carbon is identified as one, and that collectively these are significant and merit inclusion into conservation and management and strategies. It is these blended ecosystem services that have subsequently been the main focus of the project. The investigation of alternative financial approaches for the management and protection of Abu Dhabi’s Blue Carbon ecosystems were included in the Financial Feasibility Assessment. A Specialised Compensation Fund was recommended. As coastal sabkha potentially “caps” other Blue Carbon deposits, it’s removal through excavation may result in the release of carbon dioxide to the atmosphere. This finding can support informed decision making on the implications of actions affecting coastal sabkha sites’ integrity, including the planting of mangroves which may result in a net loss of carbon stocks even over long time horizons. The field-testing and development of an integrated offline Ecosystem Validation Tool to support the Mapping Toolkit for the project was incorporated into Capacity Building Training sessions and the field surveys, allowing EAD scientists to continually update the extent directly from the field, and upload these into the online Validation Tool.

Challenge/observation

Field surveys noted that coastal sabkha is often associated with algal mats.

The realisation that quantitative studies regarding the market and non-market values of ecosystem services previously undertaken in Abu Dhabi were limited to one or two examples.

Carbon stocks of Abu Dhabi’s Blue Carbon ecosystems are likely to be the largest of any ecosystem in the Emirate and therefore warrant protection on a local scale. On a global scale, however, per area values are relatively low. Current given costs of developing carbon credits in Abu Dhabi, including opportunity costs, combined with eligibility requirements and the prevailing price for international carbon credits, their development in Abu Dhabi is not recommended. The presence of carbon within the coastal sabkha was found to be sourced from buried former Blue Carbon Ecosystem layers underneath. This led to the conclusion that coastal sabkha would therefore be appropriately termed an “associated Blue Carbon ecosystem” as whilst it stores carbon, it does not sequester it. In-field recording of ground truthing- data using traditional methods of hard copy notes could benefit from updated technological advances.
